Climate change is top of the agenda when voters in Iceland head to the polls for general elections on Saturday, following an exceptionally warm summer and an election campaign defined by a wide-reaching debate on global warming.

All nine parties running for seats at the North Atlantic island nation's Parliament, or Althing, acknowledge global warming as a force of change in a sub-Arctic landscape.

The advance of lava from a volcanic eruption in Spain's Canary Islands has slowed significantly, raising doubts Thursday about whether it will fan out across the land and destroy more homes instead of flowing into the sea.

A giant river of lava slowed to four meters (13 feet) per hour after reaching a plain on Wednesday. On Monday, a day after the eruption on the island of La Palma, it was moving at 700 meters (2,300 feet) per hour.

Nearly 2,500 rare rhino horns were destroyed Wednesday in the first ceremony of its kind in northeastern India as part of an anti-poaching drive to mark World Rhino Day.

The endangered one-horned rhinoceros used to be widespread in the region but hunting and habitat loss have slashed its numbers to just a few thousand, with most now found in India's Assam state.

Six Native American tribes sued Wisconsin on Tuesday to try to stop its planned gray wolf hunt in November, asserting that the hunt violates their treaty rights and endangers an animal they consider sacred.

The Chippewa tribes say treaties give them rights to half of the wolf quota in territory they ceded to the United States in the mid-1800s. But rather than hunt wolves, the tribes want to protect them.

The two biggest economies and largest carbon polluters in the world announced separate financial attacks on climate change Tuesday.

Chinese President Xi Jinping said his country will no longer fund coal-fired power plants abroad, surprising the world on climate for the second straight year at the U.N. General Assembly. That came hours after U.S. President Joe Biden announced a plan to double financial aid to poorer nations to $11.4 billion by 2024 so those countries could switch to cleaner energy and cope with global warming's worsening impacts. That puts rich nations close to within reach of its long-promised but not realized goal of $100 billion a year in climate help for developing nations.

A small Spanish island in the Atlantic Ocean is struggling days after a volcano erupted, forcing the evacuation of thousands of people, and authorities are warning that more dangers from the explosion lie ahead.

Here is a look at the volcanic eruption on La Palma and its consequences:

Racism, the climate crisis and the world's worsening divisions will take center stage at the United Nations on Wednesday, a day after the U.N. chief issued a grim warning that "we are on the edge of an abyss."

For the first time since the COVID-19 pandemic began, more than two dozen world leaders appeared in person at the U.N. General Assembly on the opening day of their annual high-level meeting. The atmosphere was somber, angry and dire.

McDonald's plans to "drastically" reduce the plastic in its Happy Meal toys worldwide by 2025.

The burger giant said Tuesday it's working with toy companies to develop new ideas, such as three-dimensional cardboard superheroes kids can build or board games with plant-based or recycled game pieces. McDonald's said it's also exploring using recycled plastic toys to make new restaurant trays.

Several small earthquakes shook the Spanish island of La Palma off northwest Africa in the early hours of Tuesday, keeping nerves on edge as rivers of lava continued to flow toward the sea and a new vent blew open on the mountainside.

The new vent is 900 meters (3,000 feet) north of the Cumbre Vieja ridge, where the volcano first erupted on Sunday after a week of thousands of small earthquakes.

Four famous giant sequoias were not harmed by a wildfire that reached the edge of Giant Forest in California's Sequoia National Park, authorities said.

The Four Guardsmen, a group of trees that form a natural entryway on the road to the forest, were successfully protected from the KNP Complex fire by the removal of nearby vegetation and by wrapping fire-resistant material around the bases of the trees, the firefighting management team said in a statement Sunday.
